NOVELTY - A compacted wood-based graphene conductive composite material preparing method involves boiling wood with deionized water, removing the wood for freezing treatment, repeating the above process for 3-5 times until the remaining liquid after the final boil treatment is clear and transparent, drying it to achieve a wood moisture content of less than 10% under the premise of ensuring that the wood does not crack. The wood and graphene oxide are evenly and highly organically combined, followed by carrying out first vacuum impregnation for 10-30 minutes, normal pressure impregnation for 3-10 minutes, and vacuum impregnation for 5-15 minutes, performing drying process to obtain wood-based graphene oxide composite material, reducing graphene oxide distributed inside the wood to release conductive graphene to the greatest extent by placing the wood-based graphene oxide composite material in a flat-plate hot press for hot-press reduction treatment and pressing to obtain the finished product. USE - Method for preparing compacted wood-based graphene conductive composite material. ADVANTAGE - The method enables preparing compacted wood-based graphene conductive composite material with improved internal permeability, high conductivity, improved original size stability and density of wood, excellent mechanical property, wide raw material source and wide application range in the field of semiconductor field and wood, in simple manner. DETAILED DESCRIPTION - A compacted wood-based graphene conductive composite material preparing method involves boiling wood with deionized water, removing the wood for freezing treatment, repeating the above process for 3-5 times until the remaining liquid after the final boil treatment is clear and transparent, drying it to achieve a wood moisture content of less than 10% under the premise of ensuring that the wood does not crack. The wood and graphene oxide are evenly and highly organically combined, where the graphene oxide dispersion with a concentration of 1-5 mg/mL is impregnated into the treated wood under pulsed vacuum conditions, and the temperature of drying treatment is 45-60 degrees C and the moisture content of the wood is 20 plus minus 5%, the vacuum condition is that the degree of vacuum is 0.5-0.8 MPa, followed by carrying out first vacuum impregnation for 10-30 minutes, normal pressure impregnation for 3-10 minutes, and vacuum impregnation for 5-15 minutes, performing drying process sequentially in the following manner such as drying in a vacuum drying box at 45-60 degrees C for 8-12 hours, drying in a blast drying box at 45-60 degrees C for 5-7 hours, drying in a vacuum drying box at a vacuum degree of 0.02-0.06MPa, drying at 45-60 degrees C for 1-3 hours, drying in a blast drying box at 45-60 degrees C for 8-12 hours to obtain wood-based graphene oxide composite material, reducing graphene oxide distributed inside the wood to release conductive graphene to the greatest extent by placing the wood-based graphene oxide composite material in a flat-plate hot press for hot-press reduction treatment, and pressing at 180-200 degrees C for 30-75 minutes to obtain the finished product.
